Long-Range Interactions in Celestial CFT
Sangmin Choi, Ameya Kadhe, Andrea Puhm
Loop corrections in QED and gravity have recently been conjectured to give rise to an infinite tower of logarithmic soft theorems governing the universal low-energy behavior of pho…
Exact Infrared Triangle in Massless sQED with Long-range Interactions
Sangmin Choi, Ameya Kadhe, Andrea Puhm
The logarithmic soft photon theorem in four spacetime dimensions encodes an infinite-dimensional asymptotic symmetry which acts on massive matter as a divergent superphaserotation.…
The Classical Super-Phaserotation Infrared Triangle
Sangmin Choi, Alok Laddha, Andrea Puhm
The universality of the logarithmic soft photon theorem in four dimensions can be traced to an infinite-dimensional asymptotic symmetry which acts as a local phase rotation on matt…
The Classical Super-Rotation Infrared Triangle
Sangmin Choi, Alok Laddha, Andrea Puhm
The universality of gravitational scattering at low energies and large distances encoded in soft theorems and memory effects can be understood from symmetries. In four-dimensional…
Size and Shape of Rotating Strings and the Correspondence to Black Holes
Nejc Äeplak, Roberto Emparan, Andrea Puhm +1
In light of the correspondence between black holes and fundamental strings with non-zero spin, we compute the sizes of rotating strings for small, moderate, and large values of the…
